add ignore state for resources

add ignore state for resources

In this state the resource will not get touched by us, all commands
(like start/stop/migrate) go directly to the VM/CT itself and not
through the HA stack.
The resource will not get recovered if its node fails.

Achieve that by simply removing the respective service from the
manager_status service status hash if it is in ignored state.

Add the state also to the test and simulator hardware.
